Design
Loading and Arranging Machine
-
Little remaining magnetic after stacking. Stacking without disorder.
-
Stacking position adjustable. To adapt different heating requirements of leaf spring production.
-
Aligning stroke adjustable
-
Stacking and aligning motion does not interfere with walking beam furnace.
Walking Beam Furnace
-
Furnace equipped a heat exchanger. Combustion air can be heated using waste heat and improve energy efficiency.
-
There is preheating and heating zones in the furnace. The temperature of heating zones controlled by the controller.
-
Feeding machine cooperate with rolling machine.
-
Gas meter and pressure relief devices comply with relevant national standards
Descaling Facility
Transfer and Feeding System
-
Computer automatically calculates positioning length
-
Loading and unloading are synchronized
Parabolic Rolling Machine
Straightening Machine
-
The Heat Straightening Machine uses a parallelogram mechanism to maintain its ability to straighten the heated end spring leaf while the other side is cold.
-
Less indentation on the straightened side
3-Position Hydraulic Presser
Assist Robot
-
A 6-axis robot. It can catch the leaf spring for pressing processing.
-
The Specially designed hydraulic hand can provide a strong clamping force, and can run in a high temperature environment.
Cooling Collection and Stacking Machine
Number of layers per stack and number of leaves per layer can be set by PLC.
